Abstract

The acceptance and use of information technologies by target users remain a key issue in information systems (IS) research and practice. Building on past research and integrating computer self-efficacy (CSE) and perceived system complexity (SC) as external variables to the technology acceptance model (TAM), this study examines the direct and indirect effects of these two factors on system eventual acceptance and use. Overall, both CSE and SC demonstrated significant direct effects on perceived usefulness and perceived ease of use as well as indirect effects on attitude and behavioral intention. With respect to TAM’s variables, perceived ease of use demonstrated a stronger effect on attitude than that of perceived usefulness. Finally, attitude demonstrated a non-significant impact on behavioral intention. Several implications for research and practice can be drawn from the results of this study.
